For books and media resellers
Penny margins at volume. Every fee matters. We track all of them.
Books and media reselling is a numbers game. Low per-unit margins mean a single fee error or mispriced lot can wipe out a month of profit. Profit Hawk keeps the math honest — lot by lot, fee by fee.
- Per-item COGS from thrift lots, library sales, and wholesale batches
- Fee verification at the transaction level — penny errors add up at volume
- Volume analytics — know your real take-home per item when you're moving thousands

Plays nice with where you already sell.
9 cents per item on 4,000 sales is $360. Do you know where it went?
Books and media resellers live on volume. When your average margin per item is $2–$5, a 9-cent fee error doesn't feel like much — but across 4,000 transactions, that's $360 in fee leaks you never recovered. At that scale, Profit Hawk's reconciliation engine pays for itself on the first pass. And the COGS tracking tells you which categories of books actually made money and which ones you're listing out of habit.

Library sale lots made simple.
You spent $40 at the library bag sale and came home with 60 books. One lot entry in Profit Hawk: $40 total, 60 items, 67-cent cost basis per book. As each one sells, the COGS is already there. At the end of the month, you see your actual margin on the whole lot — not a rough estimate.
Fee errors at volume hit harder than you think.
At 500 transactions a month, even a 0.1% fee error rate means 5 incorrect fee charges. If each one is $2–$5, that's $10–$25 per month in leaks. Profit Hawk catches all of them — and the first month's recovery often covers the annual subscription cost of the Starter plan.
Know which categories are actually worth your shelf space.
Tag your listings by genre, format (hardcover, paperback, audiobook), and condition. Profit Hawk shows you average margin, average days-to-sell, and sell-through rate by tag. You'll stop listing paperback romance novels that sit for 60 days and double down on the vintage sci-fi that sells in 3.
